| A | B |
|---|
| Aerobic | Means oxygen is needed. |
| Anaphase | Chromosomes separate and move to opposite sides of the cell. |
| Biogenesis | All life comes from pre-existing life |
| Cell | Basic structural and functional unit of life; building block of all living things |
| Cellular | type of respiration which takes place in mitochondria |
| Cell wall | surround plant cells |
| Centromere | structure which holds duplicated chromosomes together. |
| Cheek | Cells you looked at in lab that do not have a cell wall. |
| Chemical | Evolution which probably gave rise to life |
| Chloroplasts | Green plastids in which photosynthesis occurs. |
| Chromoplasts | Give color to flowers |
| Chromosomes | Packages of genetic information found in pairs; composed of DNA |
| Cytokinesis | division of the cytoplasm into two cells; usually follows mitosis |
| Cytology | study of cells |
| Cytoplasm | Living jelly-like material. |
| Cytoskeleton | provides support; maintains the shape of the cell |
| Daughter | identical cells; result from mitosis. |
| DNA | Twisted ladder |
| ER | Transport system |
| Eukaryotic | Cells that have membrane around nucleus and organelles. |
| Golgi | Packages and modifies substance in the cell |
| Growth | increase in number and size of cells |
| Interphase | Cell grows and chromosomes duplicate. |
| Intra | Means inside. |
| Leucoplasts | Colorless plastids which function to store starch |
| Lysosomes | small sacs of digestive enzymes; "suicide bags" |
| Membrane | surrounds every cell; controls what enters and leaves the cell |
| Metaphase | Chromosomes line up in the middle of the spindle fibers. |
| Mitochondria | Site or place where energy is made in a cell; "power plant" of the cell |
| Mitosis | nuclear division that results in two identical cells. |
| Nucleolus | Functions in synthesis of RNA. |
| Nucleus | Brain |
| Onion | Slide you made in lab in which cells look like "bricks on a wall". |
| Organelles | Structures which perform important functions inside a cell; "little organs" |
| Oxygen | substance lacking in primitive atmosphere |
| Prophase | Stage of mitosis in which spindle fibers form; chromosomes become visible |
| Replication | duplication of chromosomes |
| Ribosomes | Site of protein synthesis. |
| Semipermeable | nly selected substances can pass through the membrane |
| Telophase | Membranes form around the two sets of chromosomes and two daughter cells are formed. |
| Chemoautotroph | uses chemicals in the environment to produce energy |
| Heterotrophy | obtains energy from eating other organisms or materials |
| Anaerobic | does not need oxygen to survive; without oxygen |
| Rough | type of endoplasmic reticulum which has ribosomes and makes proteins |
| Smooth | type of endoplasmic reticulum; lipid synthesis; no ribosomes |
| Ribosomes | site of protein synthesis; may be attached to ER or just in cytoplasm |
